The agricultural sector receives substantial support from livestock, which greatly contributes to the well-being of rural communities. Livestock offers animal-derived products, such as meat and milk, serve abundant protein sources for human consumption. While majority South Africa’s land is suitable livestock farming within smallholder sector, these farmers often face a variety challenges. Among challenges, there insufficient access superior forage resources, resulting in limited...
Maize silage is produced to alleviate forage shortage on dairy animals, particularly during the dry season. Microorganisms play a significant role in fermentation and thus determine quality. Therefore, modulation of microorganisms may help prohibit undesired bacteria improve Hence, this study evaluated effects tannin extract as an additive fermentative quality, aerobic stability microbial composition maize silage. mini-silo experiment with five treatments was conducted for 75 days. The...
This study evaluated the effects of barley sprout on ruminal fermentation characteristics, enteric methane emission and microbiome profiles meat-master lambs. Twelve uncastrated lambs aged 3 months were used. They randomly assigned to three dietary treatments: Eragrostis curvula hay as a control diet (T1), grass plus 25% sprouts (T2) 50% (T3). Animals fed for 61 days, including 10 days adaptation. Four animals per treatment used collect rumen fluid. Methane was recorded nine consecutive from...
Feed shortage is the main cause of poor production performance in livestock under smallholder farmer’s South Africa. Therefore, this study evaluated growth performance, nutritive value and vitro ruminal fermentation Stylosanthes scabra accessions climatic condition Pretoria, Africa as potential forage sources order to improve feed quality subsequently production. were planted 6 m2 plots following a complete randomized block design with three replicates per accession. The plants allowed grow...
Calobota sericea (Thunb.) Boatwr. & B.-E.van Wyk (Fabaceae) is a native legume from the semi-arid rangelands of South Africa. The species has been prioritised as forage for water-limited agro-ecological areas. No information regarding nutritional quality C. harvested at different phenological stages currently available, limiting our knowledge to best time harvest forage. aim this study was determine five stages. Results show that crude protein, fibre, energy and digestibility decreased with...
Natural pastures constitute a major component of ruminant livestock feed, and are the most cost-effective feed resource available for smallholder subsistence farmers. However, this does not meet animal nutritional requirement due to deficiency in nitrogen, energy minerals. In addition, at maturity lignification is concern since it reduces digestibility contributes methane emission. Thus, objective study was evaluate effect supplementing low-quality Eragrostis grass hay with five (9281,...
Inadequate supply and quality of forage, particularly during the dry season, is a major constraint to livestock production in sub-Saharan Africa (Anele et al. 2011), including South Africa. Poor management available feeds, seasonal variability weather climate change contribute high fluctuation forage quantity between seasons years (Sultan 2008). To improve production, there need both feed through use alternative crops. Stylosanthes scabra cv. Seca has been evaluated for season...
AbstractFodder tree species are considered to have high nutritional value and always played a significant role in feeding livestock during the dry seasons. The study was conducted explore possibility of preserving chopped Vachellia nilotica shoots as silage. Edible plant material V. were harvested, ensiled 1.5 L anaerobic glass jars under laboratory conditions with four treatment applications: control, + seedpods, molasses, molasses seedpods. Three per opened at Days 3, 7, 21 60 determine...
Maize silage is produced to alleviate the effects of forage shortages on ruminant animals, particularly during dry season. Microorganisms play a significant role in fermentation and thus, large extent, determine quality. The modulation microorganisms may help inhibit undesirable bacteria improve Therefore, condensed tannin extract from Vachellia mearnsii bark was used as an additive maize ensiling. Hence, this study evaluated (condensed tannin) fermentative quality, aerobic stability,...
